Background Fungal keratitis has a high incidence in China and its clinical treatment is very difficult,and its etiology diagnosis and appraisal is the premise to improve the prognosis of disease.With the changes of regional environment and climate in recent years,whether the spectrum of fungal keratitis change in South China is remarkable.Objective The purpose of this study was to investigate recent pathogenic distribution of fungal keratitis in South China area.Methods The consecutive fungal culture resuhs of 3 350 purulent keratitis at Zhongshan Ophthalmic Center from January 2009 to December 2014 were retrospectively reviewed.The positive rate of fungal culture,genus or species distribution,seasonal distribution and different term distribution were analyzed.Results The culture-positive rate was 31.34％ in this study (1 050/3 350),and the average culture-positive number was 175 strains per year.In the positive fungus,the highest positive rate was Fusarium SP (32.10％,337/1 050),and followed by Aspergillus SP (25.71％,270/1 050),Heminthosporium SP (14.29 ％,150/1 050) and Mucor SP (9.14％,96/1 050).The fungal culture-positive rate was 36.05％ (367/1 018) in 2009 to 2010,32.45％ (324/1 014) in 2011 to 2012,and 26.86％ (354/1 318) in 2013 to 2014,respectively,with a significant difference among the three periods (x2 =22.37,P＜0.01),showing a decreasing tendency of incidence.Two hundreds and sixtyone strains were isolated from January to March (31.15 ％,261/838),182 strains from April to June (25.53 ％,182/713),237 strains from July to September (30.00％,237/790),370 strains from October to December (36.67％,370/1 009),showing a statistically significant difference among them (x2 =25.19,P ＜ 0.01).The number of infectious strains was most during October to December and fewest during April to June.Conclusions The leading pathogenic fungi of fungal keratitis is Fusarium SP and followed by Aspergillus SP,Helminthosporium SP,Mucor SP in turn.Fungal keratitis is usually prevalent from October to December,and its incidence is still rising in Chinese mainland recently.However,the increasing tendency in South China has been prevented in recent six years.

Abstract: With the development of molecular biology, non-coding sRNA has been found to play an important regulatory role in gene expression and protein activity, affecting various biological pathways including mosquito resistance against insecticides. Understanding the molecular regulatory mechanisms of drug resistance is essential for controlling mosquitoes, , of which metabolic resistance being the most critical mechanism, mainly referring to the high expression of metabolic detoxification enzyme-related genes (especially the cytochrome P450 enzyme system) in mosquitoes. On the basis of verification of insecticide resistance-related genes, further research on the correlation between sRNA and mosquito resistance-related genes provides new ideas and directions for further exploring the mechanism of mosquito resistance. The study of mosquito metabolic resistance mechanism is of great significance for the control of vector mosquitoes, drug resistance monitoring and novel insecticide development. This article reviews the progress of research on the resistance genes, sRNAs biosynthesis, genes involved in regulating mosquito metabolic detoxification enzymes and their applications.

Objective: To explore the protective roll of ifbroblast growth factor 21 (FGF21) in endoplasmic reticulum stress (ERS) induced rat's H9c2 cardiomyocyte apoptosis with its mechanism. Methods: pcDNA4 was used as gene vector, pcDNA4-FGF21 plasmid was constructed and transfected into rat's H9c2 myocardiocytes for 48 h. ERS model was established by 10 μM tunicamycin (TM) induction for 24 h. The experiment was conducted in 4 groups:①Control group,②TM group, the cells were treated by TM,③pcDNA4-FGF21+TM group,④pcDNA4+TM group. The expressions of FGF21, protein kinase R-like ER kinase (PERK) and c-Jun N-terminal kinases (JNK) mediated apoptosis pathway related protein were measured by Western blot analysis; cell survival rate was examined by CCK-8 method and apoptosis rate was detected by TUNEL technique. Results: pcDNA4-FGF21 vector was successfully constructed and overexpressed in H9c2 myocardiocytes. Compared with Control group, TM group and pcDNA4+TM group had up-regulated endogenous FGF21 expression, increased PERK and JNK mediated apoptosis pathway related protein expression; reduced cell survival rate and elevated apoptosis rate. Compared with TM group and pcDNA4+TM group, pcDNA4-FGF21+TM group had down-regulated PERK and JNK mediated apoptosis pathway related protein expression; increased cell survival rate and decreased apoptosis rate. Conclusion: FGF21 overexpression can reduce ERS induced apoptosis rat's H9c2 myocardiocytes which might be partly related for inhibiting PERK and JNK mediated signal transduction of apoptosis pathway.

Objective To observe the clinical efficacy of comprehensive muscle-region therapy based on Chuang Medicine in treating cervical spondylosis of neck type.Method A hundred patients with cervical spondylosis of neck type were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by the comprehensive muscle-region therapy based on Chuang medicine (muscle-region tuina, fire-needle acupuncture of Chuang medicine, and cupping), while the control group was by regular acupuncture treatment. The Visual Analogue Scale (VAS) score and symptoms and signs scores were observed before and after intervention, and the clinical efficacies were compared.Result The VAS scores respectively after 1 and 2 treatment courses were significantly different from that before intervention in the treatment group (P<0.05,P<0.01). The VAS score after 2 treatment courses was significantly different from that before intervention in the control group (P<0.05). After 2 treatment courses, the VAS score in the treatment group was significantly different from that in the control group (P<0.05). After treatment, the symptoms and signs scores (pain intensity, pain-affected area, number of tender points, limited motion, and general score) were significantly different from that before intervention in the treatment group (P<0.01, P<0.05). In the control group, the pain intensity, limited motion and general score after treatment were significantly different from that before intervention (P<0.05,P<0.01). After treatment, the symptoms and signs scores in the treatment group were significantly different from that in the control group (P<0.05,P<0.01). The total effective rate was 100.0% in the treatment group versus 84.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Comprehensive muscle- region therapy in Chuang medicine is an effective approach in treating cervical spondylosis of neck type.

Objective To establish assay methods for the determination of dissolution,content and related substances of vita-min K1 self-nanoemulsifying drug delivery system(VK1-SNEDDS),and investigate the physico-chemical properties of the preparation. Methods The UV method was established to determine the dissolution of VK1-SNEDDS. The content and related substances were de-termined by HPLC. The appearance,self-emulsification time,micro-morphology,droplet size and zeta potential were also investigat-ed. Results The linearity range of established UV and HPLC methods was 0.85-20.4 and 2.16-216μg/ml,respectively,and all the recovery,precision,specificity and sensitivity met requirements. VK1-SNEDDS could disperse quickly after dilution. The transmission electron microscope(TEM)image of the optimized liquid SNEDDS showed that most of the emulsion droplets were of uniform size with no signs of coalescence. Droplet size of optimal formulation was revealed as 47.74 nm with polydispersibility index(PDI)of 0.248,and zeta potential was found to be-20.53 mV. Conclusion VK1-SNEDDS could form homogeneous and stable nanoemulsion when dilut-ed with aqueous phase and increase the dissolution of lipophilic drug. The methods are reliable,accurate and suitable for quality con-trol of VK1-SNEDDS.

AIM:To explore the effects of galectin-3 (GAL-3) on the viability, migration and inflammation of human umbilical vein endothelial cells (HUVECs) and the mechanisms.METHODS:The HUVECs were cultured in vitro and treated with GAL-3 recombinant protein at 2 mg/L or GAL-3 short hairpin RNA (shRNA).The HUVECs were divided into normal group, recombinant GAL-3 group, shControl group and GAL-3-shRNA group.The mRNA expression of GAL-3, monocyte chemotactic protein (MCP)-1, IL-6, matrix metalloproteinase (MMP)-9 and cyclin D1 was detected by real-time quantitative PCR,and the protein expression of GAL-3, IL-6 and MCP-1 was detected by Western blot.The secretion levels of MCP-1 and IL-6 in the culture medium were measured by ELISA.The viability and the ability of migration of the HUVECs were examined by CCK-8 assay and wound healing assay.The protein levels of heat shock protein 90 (HSP90), ERK1/2, p-ERK1/2, JNK and p-JNK were determined by Western blot.RESULTS:The expression of GAL-3, MCP-1 and IL-6 at mRNA and protein levels, the mRNA expression of MMP-9 and cyclin D1, and the secretion levels of MCP-1 and IL-6 in the culture medium were significantly higher than those in normal group (P<0.05) after the HUVECs were treated with GAL-3 recombinant protein.However, these molecules mentioned above in GAL-3-shRNA group were significantly lower than those in normal group and negative control group (P<0.05).Compared with normal group, the viability and migration ability of the HUVECs in recombinant GAL-3 group were significantly increased, but the viability and migration ability of the HUVECs in GAL-3-shRNA group were lower than those in normal group and shControl group (P<0.05).In addition, the protein levels of p-ERK1/2 and HSP90 in recombinant GAL-3 group were higher than those in normal group (P<0.05), but those in GAL-3-shRNA group were lower than those in normal group and shControl group (P<0.05).The protein level of p-JNK was not oviously changed among the 4 groups.CONCLUSION:GAL-3 is involved in regulating the cell growth, migration and the release of inflammatory cytokines in vascular endothelial cells, which may be mediated by HSP90-ERK1/2 signaling pathway.
